Another celebrity posted to their instagram a pic of their very ornate back tattoo…with the caption: “Here’s something that most people don’t know about me… Safe to say Mum wasn’t thrilled at first.”

So who’s the celeb with the crazy back tat? Find out after the jump!

It’s none other than JACK OSBOURNE!

The dude took to instagram to show off his rarely-seen tattoo, along with this selfie. Jack Osbourne looks very Lord of the Rings, just like his sister Kelly. So much so that I with both had cameos. But I guess I’ll be satisfied with the knowledge that he’s got a weird tattoo that’s going to be super embarrassing when he’s 70.
